Tools to Save Electricity

We have compiled here a list of all products and online tools and resources that we find very useful to save electricity.

Owl Wireless Electricity Monitor1. The Owl Wireless Electricity Monitor: We find this tool very helpful in tracking the complete electricity usage of a house, apartment or building. You just need to hook it up to the electricity line coming out from the meter or fusebox that the electricity company installed for you. The Owl comes in 1-phase and 3-phase options, and the sensors that are included in the box are simple clip ons that can be easily snapped around any cable line.  If you think your electricity cable is thick, you may want to buy the Large sensors, instead of the small ones.  The sensors do the actual measuring, and then wirelessly communicate the data to the monitor, shown in the image on the left. With the monitor, you can track real time how much electricity your house is using, and have better control on your bills. You can understand how my electricity your individual appliances use by turning them on and off one by one, to see their impact on the total reading.  The Owl also saves data for up to a year, and you can easily download it to your computer with a USB cable. The Owl comes with its own analysis software, which you can install on your computer to compare how your electricity usage changes by month to month, day to day and hour to hour. Prepare to be amazed by the discoveries you make about your electricity usage, especially when looking at your monitor real time. Some of the discoveries we made was that our water pump was using double its rated power consumption because it was badly in need of servicing. Also, our kitchen exhaust fan was using 4 times the electricity it should be using, and needed to be replaced. For more information, check out the Full Specifications of the Owl. Amazon has a really great deal selling it for $95 at the moment, which is 50% off the retail price.

Kill A Watt Meter2.  If you would like to measure the amount of energy (or electricity) that your individual plugged-in appliances use, instantaneously or over a period of 24 hours, than the Kill A Watt meter is for you. Plug in your appliance into the Kill A Watt, and then plug your Kill A Watt into the socket. If you know the rate of electricity you pay, you can also feed that into the meter to show you the amount of money you have spent in 24 hours to run your appliance. There is also tons of other useful information you can get, for instance what voltage are you getting at that particular socket. Just switch through the various modes to check it out. The Kill A Watt is only useful for the US, since its operating voltage is 115V.  You can buy it for $27 on Amazon.  For versions that run on 220V, here are many good options on Amazon UK. We personally prefer the Belkin Energy Saving monitor, which allows you to plug in your meter even in obscure hard to reach places, and then see your readings easily on a small wireless monitor. It can also stand loads of over 3250 Watts.

Brennenstuhl multi-socket energy meter3. If you wish to measure the electricity an entire system uses, for instance a desktop computer, a monitor and a printer, or your TV, cable box and stereo system, then look no further than the Brennenstuhl Ecoline 5-way Plug Socket Energy Monitor.  That may be a mouthful to say but it is very convenient if you wish to see, for instance, what load you have put on a single outlet. And it is wonderful for systems with multiple electricity-guzzling components. Similar to the other energy meters, you can see the instantaneous and 24-hour usage of your systems, as well as learn the current it uses, its power factor, etc.
